Retired Russian general Yevgeny Buzhinsky called for attacks on Britain with a Poseidon underwater missile that he said would trigger a 1,000ft radioactive tidal wave. 

Lt-Gen Buzhinsky, chairman of the Russian Centre for Policy Research, said Britain 'will definitely not exist' if Russia unleashed the wrath of the nuclear missile.

Buzhinsky also threatened the UK with an attack by the 14-storey high Sarmat 2, Russia's largest nuclear missile, which he claimed would destroy the country.

Vladimir Solovyov, known as 'Putin's voice', smirked as he said that if the Poseidon underwater drone hit Britain, there would be a 'tsunami'.

The warnings were made as Putin's propagandists discussed Russia's military options after its failure to make meaningful headway in Ukraine.

Buzhinsky also claimed on Russian state TV channel Rossiya 1 that the 'unstoppable' 6,670mph hypersonic missile Zircon was 'about to be used in combat operations' after testing.

'Of course, there are such means as Poseidon, which has been tested,' Buzhinsky said.

A smirking Solovyov responded: 'I would like to see how Poseidon works, I would like to see Sarmat in action.'
